Ishasha lion

A lioness taking a kip in a tree in Queen Elizabeth National Park (Southwestern Uganda). Ishasha lions are famed for tree climbing, a trait only shared with other lions in the Lake Manyara region in Uganda and Southern Tanzania. They often spend the hottest parts of the day in the ficus trees found throughout the area, probably to escape the bites of tsetse flies. It is appears to be a learnt behaviour, and so can therefore be seen as a culture trait of these lions, but it is still unclear why this behavior is rare in other lions groups.
